Why is the memory overhead for a class instance as high as 3 words (24 bytes on 64-bit systems? I find that annoyingly much for my knowledge database application. I'm aware of extern(C++), having one word overhead, but such extern(C++)-classes cannot use all of D; I get compilation errors such as

node.d(99,25): Error: Internal Compiler Error: type `inout(Edge)[]` can not be mapped to C++

Should be 2 words, the monitor and the typeinfo pointer. What is the 3rd one?

On 64-bit macos:

class C

void main()
   import std.stdio;
   writeln(typeid(C).initializer.length); // 16
